A412 ANIMAL REPRODUCTIONS. 
fingers and toes. A conical papilla becomes pers 
ceptible after amputation of the hand, which con- 
tinues to encreafe. Two fingers appear at the 
fummit, then three, and at laft four. The pa- 
pilla, in its origin, was the germ; therefore, the 
germ contained the four fingers and afl their 
concomitants. But fhould one, two, or three 
fingers be amputated, one, two, or three coni- 
cal papilla, much fmaller, will arife, and gra- 
dually afflume the figure peculiar to fingers. 
Therefore, thefe fmaller papillae were originally 
fmaller germs than thofe containing the whole 
member, and each contains only a fingle finger. 
But this is {peaking incorreCly; they do not 
properly contain a finger ; they are the finger its 
felf, contracted and concentrated into the fmal- 
left pofible fpace. It is the fame with the re- _ 
paratory germs of the hands and feet; they are 
themfelves hands and feet in extreme concentra- 
tion. But the arms, thighs, and legs, are equally 
reproduced ; therefore, there are germs which 
do not include the hands and feet alone, but alfo 
an arm or a leg. 
In the fame way, do 1 admit reparatory germs 
for replacing joints; for I cannot conceive the 
fimple mechanical formation of a joint; more 
than of a whole finger or hand. ;
